WebDuring its early growth stages and before it has become totally independent of the food stored in the seed or cotyledons, the new plant is called a seedling.

WebThe process by which new organisms grow from the seeds or similar structures is known as germination. Germination is classified into two types: Epigeal and Hypogeal germination.
